Application filed June 8, 1914.I Serial No. 843,72.

T all whom t may concern Be it known that I, ROBERT R. O L1N, a citizenof the United States, reslding at Akromin'the county of Summit'andState-.

' fication.

This invention relates to means'for automatically locating on the pinsof a rubberj heel mold the washers which are embedded in the heel to actas abutments for the heads of the nailsor screws used to attach the heelto the boot or shoe.

The invention consists in the devices hereinafter described and claimed.

l'O the accompanying drawings, Figure 1 represents a top plan view of aportion of a mold-Washering device embodying my im provements. Figs. 2vand 3 represent crosssectional views thereof on the line 2-'2 of Fig.l', showing the slide in its washer-rf ceiving and washer-dischargingpositions respectively. Fig. t represents an enlarged view of the upperend .of one of the mold ins. P In the drawings, 10 represents the bottomplate and 11 the top plate of 4a heel mold of the usual form, the topplate being the saine thickness as the heel and having cavities oropenings 12 shaped to give the heel its proper outline, and the bottomplate 10 having upstanding pins 13 which form holes in the heel betweenthe bottom face of the latter and the embedded washers, said pins beingformed at their upper ends with shouln ders 14 on which the Washers restduring the molding operation, and projections 15 'to en.V ter theapertures in the washers and center the latter on the pins. Theseprojections i prefer to make of conical or tapered form as representedin Fig'. 4 tofacilitate the drop- Y pinl of the Washers Aproperly uponthe pins.

and of suicient size to permit the passage e embodiment of my inventionherein shown consists essentially of a fixed bottom plate 16 adapted tobe'positioned over the heel mold and formedv With washerdischargingapertures 17 located above the pins 18 of the Washers, a fixed' topplate 18 formed with Washer-receiving apertures 19 out of line withthe'apertures 17 in the lowei.` plate,

and alwaslaer-feediug or transferring plate .2G in the term 'oi' a slidepresided wr-.h

washer-receiving apertures 21 adaptedV to register alternately with theapertures 19 in the upperiixed plate and the apertures 17in the lowerixed plate, this slide having the Patented Nov. 2, 19115.,

thickness of a single washer. The slide isA provided with a turned-upedge 22 to act as a handle and with stop pins 23, i tdlmit its movementin both directions', and it-is likewise suitably guided to preventlateral I I 'prefer to make 'the top i displacement. plateV 1S ofconsiderable thickness so that each of its apertures 19 acts as amagazine Washers 25 stacked one on topof the other,

.for the storage of a considerable number of excess of the washers onthe plate and removing those that did not fall into the apertures. alsoprefer te form thebottom plate 16 with extensions 26 projecting downinto the mold cavities 12, so that the aper# tures 17 form tubularguides terminating below the top of the mold-pins 13, in order cy themore effectively to guide 'the Washers onto the pins.

n the operation of this device, each-dof 1 the apertures 19 in themagazine-plate 18 is loaded with. a stack of washers, and' thevautomatic Washer-locating device compris.'-

ingy theplates 18, 19, and the slide Gis-v' placed in position over theheel mold com# prising Athe plates 10, 11., as represented in'l Fig. 2.The slidey being drawn. to the lett- 1 ward limit of its movement, thelowerniost washer in. each stack will drop into anl aparv ture 21 in theslide. Slide 20 is then shiftedA to the rightdaand. limit of itsmovement soas to 'bring its apertures 2l out of line with' the top plateapertures 19 and into line'with the bottom plate apertures 17, thewashers l954 in the `apertures 21 beingy thereby carieoln 'I' intoposition over the mold pins and dropped by gravity onto the shoulders ofsaid pins as represented in Fig. 3, the projections 15 enteringtheapertures in the washers-.Land

When the slide apertures are alined with the The Washer-placing deviceis thereuponireW wav by placingin each cavity ltlia ref i servingtorenter the latteron the pins. i

quired amount of rubber compound and squeezing it down into the cavitywith a suitable press-member or die.

lVhile it is possible to load the Washers onto the mold pins Without thepresence of the top plate 11 of the niold, l prefer to leave said topplate in position as shown, in order to avoid the accidental disturbanceof the Washers by the subsequent assembling of this top plate With thebottoni mold -plate.

It is to be understood that the invention is not confined to the exactdetails herein shown.

I claim:

l. A heel-Inold-Washering device compris` ing a plate adapted to beplaced above the cavity in a heel rnold and formed With aperturesadapted to be alined with the mold pins, and a reciprocating Washertrans ferring slide having Washer-receiving apertures movable into andout of register with the apertures in said plate.

2, A heel-Inold-wasl'iering device compris ing a plate formed withusher-receiving apertures, a second plate formed with washer-dischargingapertures, and an intermediate slide formed with washer-trans ferringapertures movable reciprocally into and out of register with theapertures in the aforesaid plates.

3. A heel-inold-wasliering device comprisingl a Washerreceiving magazineplate formed With apertures adapted to hold stacks ofwashers, aWasherdischarging plate formed with apertures' out of line iv those inthe ivasl'ier-i'eceiving plate, an( intermediate vslide having aperturesada te register alternately with those in the spective plates, andsolidv portions adapted to sustain the stacks when the slide apen ctures are alinecl with the apertures in the washer-(fiischarging plate.

4f. A lieelauoldwasiiering device cori" ing a ivaeher-discharging platelhavingD extension on its lower side formed v.' tubular apertures `lforembracing the meld pins and guiding the Washers the1eonto,and awasherfeeding slide having apertures movable into and out or line withthose said plate. i

5. The combination with a heel mold coniprising a top plate formed withmold cavities, and a bottom plate provided with washsir-supporting pinsprojecting into saiil v cavities, of an automatic ivashering device GCcomprising a fixed plate supported ontlie top plate of the niold andformed with iv:relier-discharging apertures in line with the mold-pins,and a slide on said fixed plate :formed with apertures movable into andout ot' line with those in said fixed plate.

ln testimony whereof i have hereunto set my hand in the Yin'esence oftwo subscribing uitnesses, this iltli day of June, 1914.
